Cloud bunny,
You might want to check your facts. Having resigned, I can confirm that I was advised my leave would be cancelled and that any absence due to illness would be deducted from my pay. If you want to confirm it for yourself, check the 'Rough Guide to Ryanair' - it's all in there.
So just because it didn't happen to you, don't assume that your colleagues are not being shafted (a common attitude which may go some way to explaining the current predicament of Ryanair pilots).
Enjoy your new job.
